high Nessus Plugin ID 209872

Synopsis

Fortinet Firewall is missing one or more security-related updates.

Description

The version of FortiWeb installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-21-132 advisory.

 - Multiple stack-based buffer overflows in the command line interpreter of FortiWeb before 6.4.2 may allow an authenticated attacker to achieve arbitrary code execution via specially crafted commands.
 (CVE-2021-36193)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Please upgrade to FortiWeb version 6.2.7/6.3.16/6.3.17/6.4.2/7.0.0 or later.
